OK, so I have a Samsung 226BW that is HDCP and I have a Radeon 1900xt, that is supposed to be HDCP, but the Power DVD HDCP check test, tells me that I don't have HDCP on my video output and to switch to analog. What kind of crap is this? Anyone know what is up?

It seems that if I run AnyDVD, it plays back with no problem. Interesting.
 
x1900xt?

I don't think that one had HDCP, no. Nearly 100% sure, in fact.

I think the first cards to support it from ATI where the rv570-core cards, so that would be the X1950 Pro and X1650 XT only. And, of course, the HD 2600/2900 cards and HD 38xx series off of newer cores. Granted, the x1900xt is FASTER than the x1950 Pro...but it's a much older core. Something like a year or more older, IIRC.

Have a product link?

EDIT: Did a bit of searching for you. Apparently, the only x1900xt that has HDCP support is the Asus 'EAX1900XT/HTVDP' model. No other x1900xts do, from what I can tell.
 
HDCP does not require HDMI.

Thanks for checking on the 1900xt. I was almost certain it did. It is about 2 years old anyway. It was the ATI branded, not a mfg brand like Asus, or Gigabyte. Oh well, now I have to upgrade to a new nVidia board, then Vista, then Crysis...lol. The 1900xt has been a really good gaming card too.

Thanks again.
 
I believe you also need and HD DVD hardware DVD player as well if i'm not mistaken? Unless you go with an extensive software workaround. Nor sure where I read that maybe someone with more HDCP experience can chime in. I was under the impression that one could use (example) the Xbox HD DVD player, and along with an HDCP compliant monitor, and video card, and Power DVD (or WinDVD's equivalent) version that supports HDCP then you would be fully HDCP ready.
 
You would be correct on that one. In my case I already purchased the internal BD rom from Lite-on that was on Newegg. It came with Power DVD 7.

there was a big stink about 15 months back, firingsquad ran an article rollocking ATI for advertising there cards as HDCP compatible (which the chip was), but not actually making the cards with the cryptography token.

nVidia got of a little lighter because they didn't actually make the cards, it was the vendors choice to implement the token or not.
 
the official word on the ATI website mentioned

HDCP COMPATALBLE

I assumed that ATI would have put the feature in and left it to the other mfg's to do it also, you know since ATI is all about video playback.
 
So how is it that AnyDVD can beat the HDCP check, I thought the AACS was encryption, not realted to the HDCP. Or is it that the AACS activates the HDCP check?
 
AACS is the HD media encryption algorithym protecting the disc's data from being read by unauthorized players. Once it has been decrypted and decoded for playback then it is sent over the video connection, in this case DVI, which is what HDCP protects, the actual video signal itself.

If you bypass AACS with Anydvd then you don't need an HDCP compliant connection, you can do whatever you want with the decoded content, including re-encode to another format or use non-HDCP compliant hardware for playback.

Hope that clarifies it somewhat.
 
power dvd should still play through dvi even if you fail the hdcp check. 2600pro through dvi fails hdcp check but still plays content at 1080p but may not work with x1xx cards.

Great explanation. So the AACS is like the HDCP initiating handshake in the software even before it hits the video card?

Is it best to copy the vid file then convert to another format for pc viewing. Which is best to convert to h.264?
